Book Environmental Radiation Measurements

Download or read book Environmental Radiation Measurements written by National Council on Radiation Protection and Measurements and published by Ncrp. This book was released on 1976 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In recent years, the need for accurate, reliable and interpretable measurements of environmental radiation and radioactivity has increased steadily. Such requirements as the assessment of exposure to man from natural and manmade sources, the evaluation of compliance with governmental regulations, knowledge of the movement and retention of manmade radionuclides due to man's use of such materials, and the investigation of geological processes and atmospheric phenomena have all contributed to this need. This report presents a unified and systematic consideration of environmental radiation measurements, especially with respect to the identification and characterization of smalll radiation fields and small concentrations of specific radionuclides, and the even smaller variations or changes in them. The role of measurements in the realistic assessment of dose to man through critical pathways is emphasized, serving as an introduction to the detailed discussions on sampling and sample analysis for radioactivity. Finally, the future needs and uses of environmental measurements, of new instrumentation, and of improved interpretations of the results are presented." --From Preface, page iii.

Book Calibration of X ray Ion Chambers for the Space Environment Monitoring System

Download or read book Calibration of X ray Ion Chambers for the Space Environment Monitoring System written by Arlyn Unzicker and published by . This book was released on 1974 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the steady-state of the ion-chamber current output to the incident energy flux of a monochromatic X-ray beam are reported for the 1/2-3 Å and 1-8 Å ion chambers for the NOAA Space Environment Monitoring System. Bragg crystal reflection was employed to obtain a monochromatic beam. Proportional counters were used to measure the absolute intensity of the monochromatic X-ray beam. An ultra-sensitive electrometer was used to measure the current output of the ion chamber, including currents as small as 10−15 amps with noise levels as low as about 10−16 amps. The calibration results are compared with the theoretical transfer function. The effects of anode structures on reducing the effective total area of the ion chambers were observed as a function of wavelength. The influence of small regions of epoxy overlying the window was examined.

Book Precision Environmental Radiation Monitoring System

Download or read book Precision Environmental Radiation Monitoring System written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new precision low-level environmental radiation monitoring system has been developed and tested at Jefferson Lab. This system provides environmental radiation measurements with accuracy and stability of the order of 1 nGy/h in an hour, roughly corresponding to approximately 1% of the natural cosmic background at the sea level. Advanced electronic front-end has been designed and produced for use with the industry-standard High Pressure Ionization Chamber detector hardware. A new highly sensitive readout electronic circuit was designed to measure charge from the virtually suspended ionization chamber ion collecting electrode. New signal processing technique and dedicated data acquisition were tested together with the new readout. The designed system enabled data collection in a remote Linux-operated computer workstation, which was connected to the detectors using a standard telephone cable line. The data acquisition system algorithm is built around the continuously running 24-bit resolution 192 kHz data sampling analog to digital convertor. The major features of the design include: extremely low leakage current in the input circuit, true charge integrating mode operation, and relatively fast response to the intermediate radiation change. These features allow operating of the device as an environmental radiation monitor, at the perimeters of the radiation-generating installations in densely populated areas, like in other monitoring and security applications requiring high precision and long-term stability. Initial system evaluation results are presented.

Book Handbook of Radioactivity Analysis

Download or read book Handbook of Radioactivity Analysis written by Michael F. L'Annunziata and published by Elsevier. This book was released on 2012-12-02 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Radioactivity Analysis is written by experts in the measurement of radioactivity. The book describes the broad scope of analytical methods available and instructs the reader on how to select the proper technique. It is intended as a practical manual for research which requires the accurate measurement of radioactivity at all levels, from the low levels encountered in the environment to the high levels measured in radioisotope research. This book contains sample preparation procedures, recommendations on steps to follow, necessary calculations, computer controlled analysis, and high sample throughput techniques. Each chapter includes practical techniques for application to nuclear safety, nuclear safeguards, environmental analysis, weapons disarmament, and assays required for research in biomedicine and agriculture.
